The groove 15 of the cam drum 13 consists of horizontalportionsila arranged e portions 15", and an inclined x portion 15u. A lever 16 whichis pivoted intermediate its ends as at 17 to the iframe 1,isp rovided with an angular lower end 18 travelling in thegroove 15. The lever 1G is pivotally connected at its upper end as at 19 tothelower end of a rod 2O which is connected at its upper end to the table 2. The connection between the table 2 and rod 20 is establishedhby a nut 21 which is swivelly connected 'as shown at 22 `to the sleeve 9 and threadedly engaged with the rod.` During the rotation ot the drum 18, the lower angular end 18 ot the lever 16 travels slowly from the lowest to the highest horizontal portion 15* of the groove 15, and l e the lowest horizontal portion of the groove.` The table 2 is held at rest while thelever 16 is traveli ling in ,the horizontal groove portion's15,

moves `downwardly while the levei'is travelling from one horizontal groove to another,

and will be returned to its initial position while the lever is travelling from the highest to the lowest horizontal groove portion. The number of horizontal portions 15a of the groove 15 will depend solely on the number which is mounted above the table 2 at a lat eral side of the box. The pusher block i23 is carried by a rod 24 which is slidably mounted in a bearing 25 carried bythe frame 1.

The pusher block 23 soperatedto `discharge I,

the packed box from the table 2 by a wheel 26 and a lever 27 associated with the wheel and connected to the rod 24 `by a link 28.

nThe lever 27 is pivoted between its ends `as at 29 to the. frame l. The cam wheel 26 is fixed to a horizontal shaft 30 journaled in the iframe 1, and is provided in its periphery with a groove 31 having a laterally oii'eet V- shaped portion 31d. The lower end of the lever 27 travels in the Uroove 31 and the y lever remains at rest except when it istraveling in the offset portion 31 of the groove. Zhen traveling in said offset portion, the lever 27 is rocked irst in one direction to eii'ect the operation or' the pusher block 23 in a direction to cause it to discharge the packed box from the table 2 and then moved in the oppositeldirection to eilect the return of the pusher @block 23 to its normal position. The cam wheel 26 is driven from the cam drum 13 at such a speed that the cani drum will move the table downwardly to its 'full extent and then return it to and hold it in its initial position before the cam wheel` 26 actuates the pusher 223 to eti'oct the discharge lisliing a driving connection between the cani drum 131- and cani wheel 2li comprisesa gear wheel 31 fixed to the uppei` enc of the cani drum, a shaft 32 journaled in the frame 1, a pinion 33 fixed to the shaft and meshing with the gear wheel 31, and a pinion 34 fixed to the shaft 3*' and meshing with gear wheel 35 ixed to the shaft 30,
